Abstract: SEAT SUPPORTING ASSEMBLY           Abstract A seat supporting assembly for use in vehicles and the like for resiliently supporting a seat. The seat supporting assembly includes a base which is to be secured to the vehicle and a seat support positioned vertically above the base and resiliently supported by a coil spring. The seat support-ing assembly also includes a ride height adjustment assembly and an adjust-able vertical movement stop assembly for limiting the upward vertical move-ment of the seat support. The ride height adjustment assembly includes a plurality of pivotable links extending between the coil spring and the seat sup-port. The links are connected by means of a threaded shaft and are relatively movable at their upper ends to cause vertical extension of the height adjust-ment assembly thereby causing variation in the height of the seat support. The threaded shaft projects forwardly from under the seat support and is readily accessible to the vehicle operator. The vertical movement stop as-sembly includes adjustable means for limiting the upward movement of the seat support with respect to the base. The stop assembly is adjustable to permit various ranges of vertical movement of the seat support to be consis-tent with the position of the seat support as set by the ride height adjustment assembly. The seat supporting assembly also includes means for indicating the relative positions of the ride height adjustment means and the vertical movement stop assembly so that their relative positions can be properly aligned.

Abstract: ABSTRACT OF THE DISCLOSURE          Disclosed herein is a soil aerating device which is adapted for connection to a powered vehicle, which includes a first frame rotatably supporting a drum carrying a plurality of core-forming tines adapted to penetrate the ground or turf to be aerated and remove a plug of soil and/or grass as the drum is rolled over the surface of the ground or turf, and which further includes a second frame having forward and rear portions.  The first frame is pivotally connected to the rear portion of the second frame for limited relative pivotal movement between the two frames and the forward portion of the second frame is pivotally connected to the vehicle for pivotal movement of the two frames relative to the vehicle between a raised position wherein the drum and tines are disengaged from the ground or turf and a lowered position wherein the drum is in engagement with the ground or turf.  An actuator means, such as a double-acting, hydraulically-actuated ram, connected between the vehicle and the second frame moves the two frames between the raised and lowered positions and applies a downward force on the second frame, when the two frames are in the lowered position, to thereby transfer a portion of the weight of the vehicle to the drum through the second frame, the pivotal connection between the first and second frames, and the first frame.  The pivotal connec-tion between the two frames permits the first frame and the drum to pivot relative to the second frame, thereby assuring full penetration of the tines as the drum rolls over hills and down into valleys in the ground or turf with a minimal effect on the ground-engaging traction of the vehicle wheels.

Abstract: ADJUSTABLE SWITCHING CURRENT REGULATOR       Abstract of the Invention The present invention relates to a high efficiency current regulator control circuit used to adjust and accurately control current flow in a substantially resistive load such as the low resistance filament in an electron gun of an electron microscope.  The efficiency is obtained by running a solid state device such as a transistor in a switching mode.  The present circuit represents an advantage over previous circuits which utilized a series or shunt pass regulator which dissipates power in performing the regulation function.  The present circuit utilizes a switching mode regulator which regulates by switching a fast transistor either full "on" or full "off" in response to current flow through a sensing resistor.  The ratio of "on" to "off" time determines the current transfer.  It is a requirement of the circuit that the sensing resistor be of a material having an extremely low temperature coefficient such that the current flow through the resistive element and the resulting inherent heating of the element do not substantially affect its resistive characteristics.

Abstract: ABSTRACT         A telephone switching system in which a call proces-sor and port event processor interact to control call progres-sion and switching.  The port event processor operates on a real time basis to control and sense events as represented by supervisory signals at the ports. The port event processor generates status information in response to sensed port events that are stored in a common store.  A call processor on an as-needed, non-real time basis, responds to the stored status information and generates command signals that are returned to the storage means.  The port event processor can retrieve the command signals to control events at the ports.  The port event processor senses events at the ports as represented by signals having a minimum and maximum duration, and the call processor can, by proper command signals, vary the minimum and maximum duration.
